mosses To all whom it may concern Be it lniow-nthat I,-Br7n'ro1\' C. "Coons, of Rochester, 1n the county. of Monroe and State of New York, have invented a new and useful Faring-Machine, fully set forth inathe "fOllOWll'l specification and shown in the accompanying drawings.

The present invention relates to paring machines for apples and other frint and more"particularly to that typein which the 1 article to be pared is rotatively supported and the paring knife isoaused to movein the direction of the axis of rotation of the article and atthe same timeon a curve con away with hand trimming or with special trimming devices. 1 i a To this and other ends the invention consists in certain partsandYcombinations of parts all of which will be hereinafter described, the novel features being pointed outin the appended. claims. :1

In the drawings: Figure 1 is a view of one side of the machine constructed in accordance with this'invention;, Fig. 2 is a view of the opposite side of the machine-,f F 1g. 3 is an enlarged detailed view showing I the knife in its relation tothe supporting fork and the turn table, together with adjacent parts; Figs. 4; and '5 are detailedviews: of thedrlvmg drum showing the'follower in two'positions, one before it has shifted in advance of the drum and the other after it hasw-been shifted as-will be hereinafter pointed out; Fig. 6 is an enlarged detailed new showing the turntable in oneofits extreme positions; Fig. ,7 is a detailed sectional view on the linen-a, Fig. showing I the turn table in the other extreme positlon and ig.-8 IS a detailed v1ew showingthe cooperation between thennproved knife and the supporting fork.

of the projections are engaged in the smooth periphery of the disk 13, but, at acertain point in the movement of the disk," the pro jection 14 enters between the arms of thestopping and drivemember 11 causing one of the projections 12 to enter the notch in the member 13 and, by this cooperation, ef;

footing the completion of the movement of thethree armed stopping and driving mem her, two of the projections 12. eventually again cooperating. with the smooth periphery of the disk 11. The disk 13 has a pinion 15 rigid therewithand this pinionis driven by a pinion 16 Which, in turn, meshes,

withia pinion, notshown, arranged on the shaft of the driving drum 17. a v

The driving drum has a gear 18 secured thereto and meshing-with a gear 19.,on the drive shaft 20 to which the drive pulley 21 is secured. Also arranged on the drive shaft 20 is a gear 22 whichmeshes with a small pinion 23 arranged on one end of a shaft 2%, said shaft 24: extending horizontally across the machine and having a pinion 25 at its other end for rotating the forksfthe' pinionsxf) on said forks being presentedsuc cessively to the pinion25 to be driven by the latter. I

The main frame 1 is provided with a horizontal extensi'on26 at one side of and above the reel, and, extending from the opposite side ofthe machine to the outer end of said 1 extension, is a guide rod 27 on which the carriage; 28 operates, .said carriage also being guided on the shaft 2% by means of a depending arm 29.v The'guide is so arranged that the carriage may be moved back and forth longitudinally of the fork, this inovement preferably, being produced by means of a follower 30 which operatesavithin a way 31 formedabout the drum 17 At the outer end of this carriage 28 a bracket 32 is secured by bolts 32 and on this bracket the knife turn-table is mounted to swing. This p turn-table preferably embodies a shaft 33 justably secured at one end to the lateral exlation orswinging of-t-he turn-table at the tension 40 .and being attached at the other end at 41 to the guide arm 36, said spring yieldingly holding the knife toward the article being pared. At the lower end of the stem37, a head 42 is secured, thishead being provided withtheusual knife guard 43 and with a knife 44. This knife is of novel construction having a recess ornotch 45 in one end thereof in order that the knife may be brought in; close proximity to a paring fork 8 as shown inFig. 8so that the knife edge 46 will lie above the axis of rotation of the fork. The'knife head is also formed with a depressed portion as at 47 in line with the notch in the end'of the knife for the same reason. Not only does the depression in the head and the notch in the knife permit the knife to be brought close to the fork for the purpose of insuring a better trimming of the article in proximity to the core, but, at the same: time, all danger of engagement between .the tines of the fork and the adjacent corner of the knife blade'is eliminated.

With the end in' view of effecting the oscilproper times, driving connection is estab lished between the turn-table andthe main frame. In this instance, this driving con nection is in the form of a segmental. gear "48 on the guide arm 38 meshing with the rack 49 formed on the bracket 50 which is sea cured by bolts 51 to the main frame extension 26. As the engagement between the I gear "48 and the rack 49 occurs only during 'aportion of the movement of the carriage 28, it"is desirable; to hold the turn -table against osclllation during the remaining POltlOllSl in order that the knife may be in proper position to cooperate with the ends ofthe article on the paring fork. Vith this in view, the guide arm 36 on the turn-table is provided with two converging faces 52 which are spaced at 53 from the end teeth on the" gear 48 and which are less in height than the teeth of the gear 48 as will be seen by referring to Fig. The bracket 50 is also pro vided with guide faces indicated at 54 and these guide faces are in a plane with the bases ofthe teeth on the rack and are designed for cooperation with the guide faces 52 after the gear 48 has passed out of engagement with the rack 49, the guide faces54 extendlng in type have been new, the difficulty of getting the paring knife close to the fork at the ends of the movement of the knife has caused the improper paring of the ends of the articles. With the wearing of the driving connection between the turn-tableand the main frame, this difficulty has increased and, as a consequence, with old machines a ring of the outer skin has been left on the fruit about the core, thus necessitating the employment of special help or trimmers for removing this unpared portion or the provision of a trimming attachment on the paring machines To overcome the disadvantage of this wearing action, there has been provided, in this invention spring means which acts upon the turn-table to take up thiswear and to maintain the faces and 54 in engagement after the gear 48 has passed out of engagement with the rack 49. In this instance, this spring means em b'odles a U-shaped member 56 having one arm'slotted at 57 and secured by the bolt' 32 the other armbeing free and bearing against a cam member 58 which is secured to the shaft 33. This cam member 58 has acentral curved portion which, when en gaging the spring, produces no actionon the turn-table, but at the ends of this curved portion are shoulders 59 which, when engaged by-the spring, hold the turntable against the guides 54 on the main frame. The cam member also has an arm 58 which acts as a knife stop by limiting the inward movement of the knife stem. This spring, also performs another function. upon one of the shoulders 59 as the turntable approaches the position shown in Fig. 7 and shifts the turn-table together with its supporting carriage 28 in advance of the driving mechanism, this being due to the engagement of the turn-table with the rack on the main frame. This will be seen clearly shown in Figs. 4 and 5 where the follower 30 is shown in the position it occupies immediately before the turn-table advances ahead of the drum and also immediately, after the follower has been shifted, the groove or way 31 in the drum 17 being en: larged at this point to permit a lost motion between the drum and the carriage which it drives. By this arrangement, the carriage and the turn-tablemay stand still a short time after the gear 48 has been disengaged It bears the fork.

from the rack .49 so that the knife will have time to completely pare the inner end of the article and to a. certain extent flatten the samebefore being carried away from the article. After it has remained still for the above purposmit must move away from the article very quickly and tothis end the way 31 is provided with a sharp or abruptbend 60 which produces this action.

The machine may also be provided with a coring attachmentof any suitable construction, that shown herein being one of known form and therefore no claims are made thereto. It comprises a coring spoon or blade 61 carried by a holder 62 whichis-adjustably secured by bolts 63 to a support 641-, the latter being pivotally supported at (35 on the carriage 28 and being movable on a guide 66 carried by the main frame, so as to direct the coring spoon to an article while it is being pared in order'to cut the core therefrom and to withdraw the article from the fork after paring. A pushofi' 67 pivoted at 68 rides over the article on the fork when the carriage moves in one direction-and upon I the movement of the carriage in the other direction to carry the coringspoon 61 away from. the fork, this pushoff assists the coring spoon in removing the pared article from After the article has been removed, the supporting member 64 turns about the axis by reason of the engagement of the carriage 61- with the projection (39, thus causing the article to be stripped from the spoon 61 by the doflfer'ZO.

In the operation of the'device, the fruit or article is placed by hand upon one of the forks 8 while the latter is out of paring position. The rotation of the reel 3 brings this fork in the path of the coring spoon 61 so that the fork will be driven by the gear 95. About this time, the paring knife which has beeirlocated adjacent the outer end of the fork, begins to move toward the article substantially in line with the axis of the latter by reason of the engagement of one of the faces 52 with one of the guide faces 5%.

Shortly before the gear 48 engages the rack 4-9, the knife will. be in engagement with the article to be pared, the knife yielding to correspond to the size of the article. hen the gear 18 engages the rack 49, the knife begins to move toward the inner end of the fork in an arc corresponding to the size of I thearticle, the rotation of the fork causing the skin to be removed in a spiral path about the article. I About the time: the end of the article is reached, that is, about the time the gear a8 is about to become disengaged with the rack t9, the spring 56 'actson the turntable and the carriage 28 in such a way as to advance the carriage ahead of the Lll'lV- ing drum in the manner hereinbefore described, thus permitting the carriage to re- I main stationary fora short period while the knife-is paring the inner end of the article. The abrupt shoulder 60 then comes into away fromthe article, permitting the coring spoon to complete its inward movement to cut the core after which the coring spoon is withdrawn carrying the article off the fork and the core, the latter being then ejected from the fork in the manner described.

Accordingto this invention, all wear in the driving connection between the turntable and the main frame is automatically taken'upby a spring so that the guides on the turn table are held against the guides on the main frame, thus providing a better paring of the ends of the articles. A new form of driving connection between the turntable and the carriage is provided which is not liable to breakage and which insures the turn table against turning while the gear and rack are disengaged. Thespring which takes up the wear in the driving connection between the turn-table and the main frame, also serves to shift the turn-table, and the carriage which supports it, ahead of the driving mechanism so that it is possible to hold the turn-table knife at the inner end of the fork, it having been found that when the usual paring machine is adjusted to operate on articles so positioned, it will effectively pare the ends of articles which are forced on the fork to the base of the tines or vice versa. It will also be noted that the knife head and the knife have been formed and arranged so that it is possible to have the corner of the knife operate in close proximity to the fork without injury to the fork or the knife by engagcn'ient of such parts so that a better paring of the inner end ofthe article is obtained.
